你看看 你写的对不对？？

<property name="cmService" ref="ContractManagerService" />
你这个地方 大写？
<bean id="contractManagerService" class="com.kds.service.impl.ContractManagerService" parent="contractTemplate" />

</beans>

在定义 ref 进行 。注入的时候 他会按照 名词 来查找的。。你并没有 指定 spring 以什么方式 装配 。

他会首先映射 到 名字查找。。。ref="ContractManagerService" 和 <bean id="contractManagerService"

完全不一样。。当然包空指针了。。。

还有我给你 提醒一下。。你看看 你自己的 头像 结帖率 。。。低的吓人。。。

下次如果你的结帖率 一直是这样。。你就别打算 在csdn 混了。。。

因为前几天我发过一次问题贴，一共只发过一次，没人有人留言……很抱歉，刚刚无满意结贴了。以后我会注意，谢谢提醒。
